摘要：
Dependences of electrode metal melting rate upon welding current under arc welding have been investigated. Cases of the welding process with and without the electrode metal evaporation and with the electrode preliminary heating have been considered. It is determined that application of linear approximation of the electrode metal melting rate versus welding current is more efficient, as compared with proportional approximation, since it is more accurate within the entire range of welding currents.
